Does Fan Ceng study Zhang Jizhi in calligraphy?

No. Zhang Jizhi was a famous politician and calligrapher in the Southern Song Dynasty. Although his regular script is not as beautiful as Wei, Jin and Tang Dynasties, Fan Ceng's calligraphy is not like Zhang Jizhi's, because Fan Ceng's calligraphy is very professional, with stable quality and unique accomplishment. His calligraphy appraisal standard is very clear. After the calligraphy is written, you can see at a glance that it was written by Fan Ceng, and there is no inscription.
